Heat insulating pattern



FIG. 1 is a plan view of the heat insulating pattern incorporating our new design of the heat insulating surface of a trivet, which surface has a repeating heat insulating pattern repeating throughout such surface as shown schematically by the solid lines, which repeating pattern incorporates our new design;

FIG. 2 is a plan view of the heat insulating pattern incorporating our new design of a heat insulating surface of a mitt, which surface has a repeating heat insulating pattern repeating throughout such surface as shown schematically by the solid lines, which repeating pattern incorporates our new design;

FIG. 3 is a plan view of the heat insulating pattern incorporating our new design of a heat insulating surface of a second mitt, which surface has a repeating heat insulating pattern repeating throughout such surface as shown schematically by the solid lines, which repeating pattern incorporates our new design;

FIG. 4 is a plan view of the heat insulating pattern incorporating our new design of a heat insulating surface of a third mitt, which surface has a repeating heat insulating pattern repeating throughout such surface as shown schematically by the solid lines, which repeating pattern incorporates our new design; and,

FIG. 5 is an enlarged sectional view through the line 5—5 of FIGS. 1, 2, 3 and 4.

The broken line showing of environmental structures in FIGS. 1-4 is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for the heat insulating pattern, as shown and described.
